T-piece press - reduced, 32 x 40 x 32

Product detailed description

Press T-pieces are essential components in the installation of heating and plumbing systems, particularly where branching or connecting pipes of different diameters is required. This model is commonly used in residential and commercial buildings for the installation of heating circuits, hot and cold water distribution, and other pressurised pipe systems. Installers and technicians working with ALPEX pipes will find this T-piece suitable for applications involving moderate temperatures and pressures, such as underfloor heating, domestic hot water supply, and central heating systems. The nickel-plated brass construction ensures corrosion resistance and long-term durability in environments where thermal expansion and contraction are common.

The T-piece allows for the connection of three pipe lines in a T-configuration, with one branch having a reduced diameter. It is used to create a junction where a smaller-diameter pipe connects to a larger one, maintaining system integrity and flow efficiency. The press connection method ensures a secure and leak-free joint, suitable for both new installations and system modifications. The design is intended for use in systems where thermal stability and mechanical strength are critical, such as in underfloor heating loops or domestic hot water circuits.

The operating temperature of +120°C and a nominal pressure of PN10 are key factors in the selection of this T-piece. These parameters determine the suitability of the component for hot water and heating systems, where the temperature and pressure levels must remain within safe limits. The material, nickel-plated brass CW617N, provides good resistance to corrosion and mechanical stress, making it suitable for long-term use in pressurised systems. The PN10 rating indicates that the fitting is designed for medium-pressure applications, commonly found in residential and commercial plumbing and heating systems.

Installation and connection

The press T-piece is installed using a press tool compatible with ALPEX pipe systems. The connection sizes are 32 mm, 40 mm, and 32 mm, allowing for the connection of pipes with different diameters in a single junction. The installer must ensure that the pipe ends are clean and free from burrs before inserting them into the fitting. The press tool applies pressure to the stainless steel sleeve, compressing the EPDM sealing ring and creating a secure joint. It is important to verify that the press tool is correctly calibrated and that the tooling is compatible with the fitting type (B-F-TH). Common installation mistakes include using incorrect tooling, failing to clean the pipe ends, or applying insufficient pressure during the pressing operation, which can lead to leaks or joint failure.

Compatibility and accessories

This T-piece is specifically designed for use with ALPEX pipes and must be used in conjunction with press tools of the correct type. It is compatible with other press fittings and valves in the same system. For a complete installation, the installer should also have access to a suitable press tool, cutting tools for pipe preparation, and cleaning tools to ensure the pipe ends are free from debris. No additional sealing materials are required, as the EPDM sealing ring is integrated into the fitting. Related products include other press T-pieces, elbows, and couplings from the same brand and system type.

Technical background for designers

The press T-piece operates by compressing the stainless steel sleeve around the pipe and sealing ring, creating a tight and durable joint. The nickel-plated brass body provides good thermal and mechanical stability, while the EPDM sealing ring ensures a watertight connection. The material properties of CW617N brass allow it to withstand thermal cycling and mechanical stress without significant deformation. The fitting is designed to integrate into pressurised systems where thermal expansion is a factor, and its PN10 rating ensures it can handle the typical operating pressures of such systems. The service life and efficiency of the fitting depend on correct installation, the quality of the press tooling, and the maintenance of the system's pressure and temperature within specified limits.

Service and operation

Once installed, the press T-piece requires no regular maintenance. However, it is important to periodically check the system for leaks or signs of wear, especially in areas where the system is subject to frequent thermal expansion or vibration. The integrity of the joint should be visually inspected during routine maintenance, and any signs of corrosion or deformation should be addressed immediately. Since the fitting is a one-time press connection, it cannot be disassembled for inspection or repair without replacing the entire fitting and associated pipe sections. No service intervals are specified in the product data, and the fitting is intended for long-term use without scheduled maintenance.

Frequently asked questions

Can the T-piece be used with copper pipes?
No, this press T-piece is specifically designed for use with ALPEX pipes and is not compatible with copper or other pipe materials.

Is the fitting suitable for hot water systems?
Yes, the maximum operating temperature of +120°C makes it suitable for hot water systems, including domestic hot water and heating circuits.

Can the T-piece be used in a system with a pressure higher than PN10?
No, the nominal pressure rating of PN10 must not be exceeded. Use in higher-pressure systems could lead to failure of the joint.

What press tool types are compatible with this fitting?
The fitting is compatible with press tools of the B-F-TH type. It is important to use the correct tooling to ensure a secure and leak-free connection.
